question Re: hadoop.rpc.protection = privacy in Support Questions https://community.cloudera.com/t5/Support-Questions/hadoop-rpc-protection-privacy/m-p/311392#M224630 Hello there,The below property would be required if you would like to set RPC encryption[1]:hadoop.rpc.protection = privacyauthentication : authentication only (default); integrity : integrity check in addition to authentication; privacy : data encryption in addition to integrity RPC encryption [2]:The most common way for a client to interact with a Hadoop cluster is through RPC.  A client connects to a NameNode (NN) over RPC protocol to read or write a file. RPC connections in Hadoop use Java’s Simple Authentication & Security Layer (SASL) which supports encryption. When hadoop.rpc.protection property is set to 'privacy' the data over RPC is encrypted with symmetric keys.  Ref: [1] https://docs.cloudera.com/HDPDocuments/HDP3/HDP-3.1.5/configuring-wire-encryption/content/enabling_rpc_encryption.html  Kindly check the below Additional references for Wire Encryption and RPC Encryption blog post with detailed explanation[3]:Ref: [2] https://docs.cloudera.com/HDPDocuments/HDP3/HDP-3.1.5/configuring-wire-encryption/content/wire_encryption.html  Ref: [3] <A href="https://blog.cloudera.com/wire-encryption-hadoop/ " target="_blank">https://blog.cloudera.com/wire-encryption-hadoop/ </A>Ref: [4] Apache Jir Ref: Hadoop in Secure Mode:https://hadoop.apache.org/docs/r2.8.0/hadoop-project-dist/hadoop-common/SecureMode.html  Hope this helps!
